Built for the most demanding tasks
As the largest material handler in the lineup, the Doosan® DX300MH-5 is built for the most demanding material handling functions. It features a fixed 6 ft. cab riser with hydraulic tilt, straight boom and droop nose stick, sandwiched counterweight, rotate grapple ready hydraulics, and additional guarding.
In addition to four power modes, the DX300MH-5 includes lifting work mode, which provides increased pump torque, low engine RPMs, and an automatic power boost.
Careful design, high-pressure common rail fuel injection and four valves per cylinder deliver increased torque and efficient fuel consumption. High-capacity pumps improve productivity, while the swing drive provides rapid cycles.
Cooling features of the DX300MH-5 include a variable speed fan and a split cooling system, which utilizes both hydraulic oil and engine coolant.
Tier 4 Technology
To reach Tier 4 emissions standards, the DX300MH-5 incorporates a high-pressure common-rail (HPCR) fuel delivery system as well as cooled exhaust gas recirculation (CEGR) combined with a diesel oxidation catalyst (DOC) and selective catalyst reduction (SCR).
